MANUFACTURE OF BRIQUETS- Application filed January 81, 1905.

To all whom it may concern.-

Be it known that we, l/VILLIAM SIMPKIN, a citizen of the United States, residing at VVestminster, and JAMES B. BALLANTINE, a subject of the King of Great Britain, residing at Twickenham, in the county of Middlesex, England, have invented certain new and useful Improvements in the Manufacture of Briq uets, of which the following is a specification.

Our invention relates to improvements in the manufacture of briquets, more particularly it has reference to the materials used as binders and the manner in which same are employed.

Heretofore briquets have generally been made with coal-tar pitch and other materials of this class as binders; but for various reasons, among which is the rise in price of these materials of late, their use is somewhat restricted.

One of the main objects of our invention, therefore, is to produce a satisfactory briquet which may be manufactured cheaply and overcome objections in the briquets made in the usual manner, as those of odor and smoke. To this end we prefer to take blood as it comes from the slaughter-house and treat it either by beating by paddles in a mixing-tank or by mixing it with a solution of nitrate of potassium, say about fifteen to twenty pounds of nitrate per ton of blood, and thus prevent the fibrin and serum from separating. We do not wish to be understood as confining ourselves to the use of these methods, as nearly all carbonates and acetates of the alkalies and most weak acids maintain the fluidity of the blood and it is desirable to maintain the blood in such a condition that it will run freely, so that it can be handled easily and cheaply.

After the blood has been prepared in either of the above ways we may prepare our briquets by mixing with the blood coal or other desirable material which has been brought to the desired degree of fineness. In the preparation of the coal briquets we prefer to mix from about one hundred to two hundred pounds of the blood per ton of coal. At the same time we prefer to also mix with the coal or'other material about ten pounds Specification of Letters Patent.

of powdered resin for every hundred pounds of blood used. The mixture thus formed is thoroughly mixed together in a cold state and afterward formed into briquets of any de sired size or shape by any well-known means. After formation the briquets are heated in an oven having a temperature of about 250 Fahrenheit for a length of time to be determined by their size, the object being to have .the heat thoroughly penetrate to the center of each briquet. The heat coagulates the blood, rendering it insoluble in water, and at the same time the resin melts and combines with it, forming a series of so-called resinates with the albuminoids, which not only prevent putrefaction, but does away entirely with the odor that would otherwise make the use of blood of no value as a binder for fuel.

Where it is desired to make an extra strong briquet and where the resulting ash would be of no value, from twenty to thirty pounds of slaked lime per ton of coal or other material to be briqueted can be added to the mixture with advantage.

Modifications may be made without de-I7 5 parting from the spirit of our invention.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is.

1. In fuel, blood and coal-dust in the proportion of one hundred to two hundred pounds of blood to a ton of coal, fifteen to twenty pounds of nitrate of potassium to every ton of blood, and about ten pounds of resin to every hundred pounds of blood.

2. In fuel, blood and coal-dust in the pro portion of one hundred to two hundred pounds of blood to a ton of coal, fifteen to twenty pounds of nitrate of potassium to every ton of blood, about ten pounds of resin to every hundred pounds of blood, and twenty to thirtypounds of slaked lime to every ton .of coal.

In testimony whereof we affix our signatures in the presence of two witnesses.
